Rate of Neointimal Coverage in Zotarolimus-Eluting Stents at 3-Month Follow-Up
The rate of neointimal coverage was nearly 100% in optical coherence tomography (OCT) but only 25% in intravascular ultrasound (IVUS). The percent neointimal coverage was defined as the measurement of circumferential stent length covered with NIH divided by stent perimeter at every 0.5-mm cross-sectional image throughout the stented segment in IVUS (6). The rate of neointimal coverage is expressed as a mean ± SD (median). ACS = acute coronary syndrome; SA = stable angina.
